Abstract
A 59-year-old patient with dilated cardiomyopathy and incessant ventricular tachycardia leading to progressive cardiogenic shock is presented. Due to hemodynamic instability, high dose catecholamines were required in addition to the implantation of an intraaortic balloon pump (IABP), which, however, appeared to further augment the frequency and duration of ventricular tachycardias. The implantation of a microaxial blood pump allowed catecholamine administration to be terminated, thereby, ending this vicious circle of catecholamine-driven electrical storm. Within 5days, the patient was hemodynamically stabilized and kidney and liver function recovered with the support of intensive antiarrhythmic therapy (amiodarone, mexiletine, sotalol). During a 24-month follow-up, the patient had no further ICD shocks and no rehospitalization was required for treatment of congestive heart failure.
